High-speed pluggable optical transceivers with advanced functionality

Abstract

An optical transceiver configured to operate in a host device includes an electrical interface communicatively coupled to the host device to interface electrically with the host device, wherein the optical transceiver is compliant with a Multi-Source Agreement (MSA) which is supported by the host device; optical transceiver components communicatively coupled to the electrical interface, wherein the optical transceiver components are configured to optically interface signals with a second optical transceiver to form an optical link; and electronic dispersion compensation circuitry communicatively coupled to the optical transceiver components and configured to electronically compensate for optical fiber chromatic and / or polarization mode dispersion associated with the optical link, separate and independent from the host device.

AI Technical Summary

Benefits of technology

Enables carrier-grade performance monitoring and error correction without the need for external transponders, extending the application of optical transceivers from short interconnects to metro and core networks, enhancing reliability and efficiency.

Problems solved by technology

Advantageously, this enables interoperability among equipment vendors of optical transceivers, i.e., any MSA-compatible optical transceiver can be used in any host system designed to the MSA specification; however, these tightly defined characteristics limit the performance of optical transceivers since the MSA specifications were designed to maximize density and minimize cost, and not to provide advanced optical performance or other integrated functions.
